摘要/Abstract

摘要：

土壤热通量在地表能量交换中扮演着重要角色，干旱半干旱区土壤热通量更加重要。利用张掖国家气候观象台的土壤热通量观测资料，分析了不同天气状况下戈壁土壤热通量的日变化特征及其与辐射通量的关系。结果表明：晴天大气向土壤传递热量，阴天和雨天土壤释放的热量大于获得的热量。另外还分析了土壤热通量季节和年变化特征。在秋冬季节，土壤热通量基本处于负值而春夏则刚好相反。

Abstract:

Soil heat flux plays an important role in energy flux exchange between land and atmosphere, especially in arid and semi-arid region. Based on soil heat flux at Zhangye National Climate Observatory, the diurnal variation of soil heat flux and the relationship between that and radiation flux are analyzed under different weather conditions for clear, cloudy and rainy day.The results show that the soil accepted heat from the air on clear day, on the contrary, the output heat of soil exceeded the input on cloudy and rainy day. In addition, most values of soil heat flux are negative in autumn and winter season, and positive in spring and summer .
